您好，我有以下错误：

malloc:*对象0x2087000的错误：未分配要释放的指针 *在malloc\u error\u break中设置断点以进行调试

我不知道那是什么东西。我不知道怎么找到它。有人能给我解释一下如何（以及在哪里）使用malloc_历史吗。我在malloc\u error\u break中设置了一个断点，但我无法找到该地址处的对象。在从nsmutablearray中删除对象并手动弹出视图控制器后，我收到了此消息。如果我注释掉[reviewUpload.images removeObject:self.reviewUploadImg]这一行，它不会给我错误，但它当然对我没有用

- (void) removeImage { debugLog(@"reviewUploadImg %@", self.reviewUploadImg); debugLog(@"reviewUpload %@", self.reviewUpload); debugLog(@"reviewUploadImg thumb %@", self.reviewUploadImg.thumb); [reviewUpload.images removeObject: self.reviewUploadImg]; [self.navigationController popViewControllerAnimated:TRUE]; } -（无效）删除图像 { 调试日志（@“reviewUploadImg%@”，self.reviewUploadImg）；调试日志（@“reviewUpload%@”，self.reviewUpload）；调试日志（@“reviewUploadImg thumb%@”，self.reviewUploadImg.thumb）； [reviewUpload.images-removeObject:self.reviewUploadImg]； [self.navigationController PopViewControllerInitiated:TRUE]； } 我试图打印出3个地址，但它们都不是被释放但未分配的地址

我从UIImagePickerController添加图像

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { UIImage *pickedImage = (UIImage *)[info objectForKey: UIImagePickerControllerEditedImage]; if (!pickedImage) pickedImage = (UIImage *)[info objectForKey: UIImagePickerControllerOriginalImage]; if (!reviewUpload.images) reviewUpload.images = [[NSMutableArray alloc] initWithCapacity: 5]; //UIImage *thumbImage = [pickedImage copyResizedImage: CGSizeMake(120, 120)]; UIImage *thumbImage = [pickedImage copyResizedImage:CGSizeMake(120, 120) withPaddingColor: [UIColor lightGrayColor]]; ReviewUploadImage *rui = [[ReviewUploadImage alloc] init]; rui.thumb = thumbImage; [thumbImage release]; NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init]; [dateFormatter setDateFormat: @"yyyyMMddHHmmssSS"]; NSDate *date = [NSDate date]; NSString *tmpFileName = [dateFormatter stringFromDate: date]; [dateFormatter release]; NSString *path = [NSTemporaryDirectory() stringByAppendingPathComponent: tmpFileName]; NSData *imageData = [[NSData alloc] initWithData: UIImageJPEGRepresentation(pickedImage, 0.90)]; [imageData writeToFile: path atomically: TRUE]; [imageData release]; rui.path = path; [reviewUpload.images addObject: rui]; debugLog(@"rui rc %i", rui.retainCount); [rui release]; [self dismissModalViewControllerAnimated:TRUE]; } -（void）imagePickerController:（UIImagePickerController*）picker未使用信息完成PickingMediaWithInfo:（NSDictionary*）信息 { UIImage*pickedImage=（UIImage*）[info-objectForKey:UIImagePickerControllerEditedImage]；如果（！pickeImage） PickeImage=（UIImage*）[info objectForKey:UIImagePickerController原始图像]；如果（！reviewUpload.images） reviewUpload.images=[[NSMutableArray alloc]initWithCapacity:5]； //UIImage*thumbImage=[PickeImage copyResizedImage:CGSizeMake（120120）]； UIImage*thumbImage=[PickeImage copyResizedImage:CGSizeMake（120120）with PaddingColor:[UIColor lightGrayColor]]； ReviewUploadImage*rui=[[ReviewUploadImage alloc]init]； rui.thumb=thumbImage； [拇指图像发布]； NSDateFormatter*dateFormatter=[[NSDateFormatter alloc]init]； [日期格式化程序setDateFormat:@“yyyymmddhhmmsss”]； NSDate*日期=[NSDate日期]； NSString*tmpFileName=[dateFormatter stringFromDate:date]； [日期格式化程序发布]； NSString*path=[NSTemporaryDirectory（）stringByAppendingPathComponent:tmpFileName]； NSData*imageData=[[NSData alloc]initWithData:UIImageJPEGRepresentation（PickeImage，0.90）]； [imageData writeToFile:原子路径：TRUE]； [图像数据发布]； rui.path=path； [reviewUpload.images addObject:rui]；调试日志（@“rui rc%i”，rui.retainCount）； [发布]； [self dismissModalViewControllerAnimated:TRUE]； } 我认为我在这里没有任何错误：ReviewUpload有一个图像数组，其中可能包含ReviewUploadImage对象。在这些类的实现中，我只有release方法，我只释放我必须释放的成员

@interface ReviewUpload : NSObject { NSString *title; NSString *tags; NSString *text; NSInteger rating; NSMutableArray *images; NSInteger idCompany; NSInteger idProduct; } @property(nonatomic, copy) NSString *title; @property(nonatomic, copy) NSString *tags; @property(nonatomic, copy) NSString *text; @property(nonatomic, assign) NSInteger rating; @property(nonatomic, retain) NSMutableArray *images; @property(nonatomic, assign) NSInteger idCompany; @property(nonatomic, assign) NSInteger idProduct; @end @接口评审wupload:NSObject { NSString*标题； NSString*标签； NSString*文本； NSInteger评分； NSMutableArray*图像；恩森特格公司； NSInteger-idProduct； } @属性（非原子，副本）NSString*标题； @属性（非原子，复制）NSString*标记； @属性（非原子，复制）NSString*文本； @属性（非原子，分配）集成器评级； @属性（非原子，保留）NSMutableArray*图像； @不动产（非原子，转让）NSInteger idCompany； @属性（非原子，赋值）NSInteger idProduct； @结束 @接口评审wuploadImage:NSObject { UIImage*拇指； NSString*路径； } @属性（非原子，保留）UIImage*thumb； @属性（非原子，复制）NSString*路径； @结束难道没有一种简单的方法可以从地址中获取objective-c对象吗

更新：如果我删除这两行中的任何一行，我都不会得到错误。我不知道该说什么这真的很奇怪

[reviewUpload.images removeObject: self.reviewUploadImg]; [self.navigationController popViewControllerAnimated:TRUE]; [reviewUpload.images-removeObject:self.reviewUploadImg]； [self.navigationController PopViewControllerInitiated:TRUE]；更新：如果在“didFinishPickingMediaWithInfo”中选择的图像为零，则不会显示错误。也许这与我创建缩略图的方式有关。下面是创建它的方法。如果有人有任何想法，请帮忙

-(UIImage *) copyResizedImage:(CGSize) thumbSize withPaddingColor: (UIColor *) bgColor { CGFloat resizedProp = thumbSize.width / thumbSize.height; CGFloat imageProp = self.size.width / self.size.height; CGSize newSize; CGFloat factor; if (imageProp > resizedProp) //image is wider factor = thumbSize.width / self.size.width; else factor = thumbSize.height / self.size.height; newSize.width = self.size.width * factor; newSize.height = self.size.height * factor; NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; UIImage *resizedImage; UIGraphicsBeginImageContext(thumbSize); CGContextRef drwContextRef = UIGraphicsGetCurrentContext(); CGContextSetFillColorWithColor(drwContextRef, bgColor.CGColor); CGContextFillRect(drwContextRef, CGRectMake(0, 0, thumbSize.width, thumbSize.height)); CGRect imageRect = CGRectMake( (thumbSize.width - newSize.width) / 2.0, (thumbSize.height - newSize.height) /2.0, newSize.width, newSize.height); [self drawInRect:imageRect]; resizedImage = UIGraphicsGetImageFromCurrentImageContext(); // this is autoreleased and i dont need it UIGraphicsEndImageContext(); [resizedImage retain]; [pool release]; return resizedImage; } -（UIImage*）copyResizedImage:（CGSize）带填充颜色的拇指大小：（UIColor*）bgColor { CGFloat resizedProp=thumbSize.width/thumbSize.height； CGFloat imageProp=self.size.width/self.size.height； CGSize； CGF浮动因子； if（imageProp>resizedProp）//图像更宽系数=thumbSize.width/self.size.width；其他的系数=thumbSize.height/self.size.height； newSize.width=self.size.width*因子； newSize.height=self.size.height*因子； NSAutoreleasePool*池=[[NSAutoreleasePool alloc]init]； UIImage*调整大小图像； UIGraphicsBeginImageContext（拇指大小）； CGContextRef drwContextRef=UIGraphicsGetCurrentContext（）； CGContextSetFillColorWithColor（drwContextRef，bgColor.CGColor）； CGContextFillRect（drwContextRef，CGRectMake（0,0，thumbSize.width，thumbSize.height））； CGRect imageRect=CGRectMake( （thumbSize.width-newSize.width）/2.0，（thumbSize.height-newSize.height）/2.0，newSize.width，newSize.height）； [self drawInRect:imageRect]； resizedImage=UIGraphicsGetImageFromCurrentImageContext（）；//这是自动删除的，我不需要它 UIGraphicsSendImageContext（）； [重新调整图像保留]； [池释放]；返回resizedImage； }

当对象从数组中删除时，将发送一条dealloc消息。查看ReviewUploadImage类的dealloc函数。我看到你有一些拇指会员在那里。C -(UIImage *) copyResizedImage:(CGSize) thumbSize withPaddingColor: (UIColor *) bgColor { CGFloat resizedProp = thumbSize.width / thumbSize.height; CGFloat imageProp = self.size.width / self.size.height; CGSize newSize; CGFloat factor; if (imageProp > resizedProp) //image is wider factor = thumbSize.width / self.size.width; else factor = thumbSize.height / self.size.height; newSize.width = self.size.width * factor; newSize.height = self.size.height * factor; NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; UIImage *resizedImage; UIGraphicsBeginImageContext(thumbSize); CGContextRef drwContextRef = UIGraphicsGetCurrentContext(); CGContextSetFillColorWithColor(drwContextRef, bgColor.CGColor); CGContextFillRect(drwContextRef, CGRectMake(0, 0, thumbSize.width, thumbSize.height)); CGRect imageRect = CGRectMake( (thumbSize.width - newSize.width) / 2.0, (thumbSize.height - newSize.height) /2.0, newSize.width, newSize.height); [self drawInRect:imageRect]; resizedImage = UIGraphicsGetImageFromCurrentImageContext(); // this is autoreleased and i dont need it UIGraphicsEndImageContext(); [resizedImage retain]; [pool release]; return resizedImage; }
